Letters Patent No. 108,146, dated October 1 1, 1870.

IMPROVEMENT IN WATERCLOSET HOPPERS.

The Schedule referred to in these Letters Patent and making part of thesame.

To alt whom it may concern Be it known that I, ALFRED Ivens, of the cityand State of' New York, have invented and made a new and usefulImprovement in Water-closet Hoppers; and I do hereby declare thefollowing to be a full, clear, and exact description of the saidinvention, reference being had 'to the annexed drawing, making .partvof'this specification, wherein I have represented a vertical section of'the said hopper.

Hoppers for water-closets have heretofore been made with a horn, forsupplying water, and with sides tapering down to the discharge-pipe,which pipe connects with or is` formed as a trap, for preventing smellpassing out of the sewer-pipe, butin these traps there is frequently anaccumulation that stops up the trap, and, if' the water. is allowed torun into the closet, there is an over-How' of very offensive material.lhis contingency is especially likely to happen where there is aperiodic-a1 dow of water into the closet from a cistern, such as shownin Letters Patent granted to me October 23, 1866.

My present invention is to remove all risk of over- Bow from "thestoppage of water-closet traps.

My invention consists in combining with a watereloset hopperI a primaryand secondary overflow, so constructed and arranged that paper or oatiugsubstances lcannot obstruct the primary overdow, and the ysecondaryoverdow is so arranged that if the primary overflow becomes obstructedby accumulation of" substances that remain partially in suspension i-uthe water, the secondary overflow may be Aavailable,` and this secondaryovero also supplies a small quantity of" fresh water, from time to time,to the trap' of the overow, to keep that water from becoming' offensive;itvbeing understood that neither the primary` nor secondary overflow arebrought into use except when themain trap of the water-closet isobstructcd.

In the drawinga represents the ring ofthe hopper, surrounding thenpper'eud, and into which the vat-er is supplied 'from a horn, in theusual manner.

b b are the inclined sides of the hopper, tapering down to the dischargeof` soil-pipe o.

dis the ange at the base, supporting the watercloset. Y

At one side of the hopper is the lprimary overflow c, leading into theascending pipe f, that connects withthe horn g, and over this is thesecondary overiow opening h. v

It is to be understood that from the horn g a pipe leads away to thesewer-pipe below the main trap; and that in this pipe a trap isintroduced. The trap is illustrated by dotted lines at k.

It will .now be seen that if' the main trap is stopped, and the waterrises in the hopper, any substance that may float will passby theprimary opening e, because there is no current running through the sameuntil the water rises as high as the line x; and, hence, material oatingouthe suri'ace will romain and not obstruct the ovcrfiow. Y

If' from any canse the primary overflow e may become obstructed, thewater may rise, and the secondary overfiow h then becomes operative.

Under ordinary circumstances there is suicieut clear water runnin gthrough this secondary opening h, from the wash of' the closet, to keepthe primary opening e clean, and also to change the water from time totime in the trap of the overfio\v pipe.

I claim as my inventiou- The overflow horn y and Vprimary and secondaryopenings c and h, introducedinto and combined with the water-closethopper l), and supply-water ring a, in the manner specified, so thatwater, in washing the closet, passes into the opening la, for thepurposes specified. f

In witness whereof, I have hereunto set my signa turc this 7th day of'February, AVD. 1870.

ALFRED IVERS.
